Book excerpt: Understanding Africa is critical for all concerned with the world today: in what promises to be his final great work of reportage, one of the keenest observers of the continent surveys the effects of belief and religion on the disparate peoples of Africa. The Masque of Africa is Nobel Prize-winning V. S. Naipaul's first major work of non-fiction to be published since his internationally bestselling Beyond Belief. Like all of Naipaul's great works of non-fiction, The Masque of Africa is superficially a book of travels — full of people, stories and landscapes he visits — but it also encompasses a larger narrative and purpose: to judge the effects of belief (whether in indigenous animisms, faiths imposed by other cultures, or even the cults of leaders and mythical history) upon the progress of civilization.
